Unpacked Learning Goal:
National Science Standard: Specialized cells perform specialized functions in multicellular organisms. Groups of specialized cells cooperate to form a tissue, such as a muscle. Different tissues are in turn grouped together to form larger functional units, called organs. Each type of cell, tissue, and organ has a distinct structure and set of functions that serve the organism as a whole.
1. What does this standard mean?
Organs are made through a complex cycle beginning with specialized cells.
When cells cooperate they in turn form a tissue.
Once a tissue is made, depending on where it is located, it groups together with like-tissues to form complex organs.
Organs (such as the brain) have distinct structures and functions in a way that is beneficial to the entirety of the human body.
Cells, Tissues and Organs have their own set of functions, but together benefit the body as a whole.
2. What prior knowledge do students need to understand the standard?
Students need to understand that the cell is the smallest functioning structural unit of life.
Students need to know the make-up of cells, ex. organelles, cytoplasm, etc.
Students need to understand the difference between animal and plant cells.
Students need to know that in order for cells to become more cells they need to undergo some sort of process.
Students need to understand that cells work together with other cells.
Students need to know what a bodily tissue is.
Students need to know what a bodily organ is and how it has specific functions which contribute to life.
Students need to be able to classify organs, for example, the brain.
Students need to understand that this one organ in particular is crucial to sustain life.
Students need to understand that the Brain (organ) is made up of subsections which contribute to the different functions in the body. (ie: hearing, seeing, etc.)
3. What misconceptions might students have around the topics contained in the standard?
Students may think that a tissue is made of one single cell.
Students may think that a tissue is an organ. (technically speaking)
Students may think that the brain is not an organ.
Students may think that the cycle of specialized cells turning into tissues which in turn become organs is not crucial to the human body as a whole.
Students may think that cells do not under go any process to replicate, but may, however, think that all the cells we need are constantly there in an inactive state until needed.
